1: Piano skills: One of the necessary conditions for piano improvisational accompaniment is piano skills. People who cannot play the piano will not play accompaniment on the piano. But it must be clear that piano skills are by no means equal to accompaniment skills. There is an essential difference between the two: the former relies mainly on mechanical exercises to reproduce the content of the music score, while the latter uses creative labor to complete the task of song accompaniment, making it a The songs complement each other as a whole. 2: Harmony basics: Improvisational accompaniment belongs to the multi-part category, and of course requires a harmonious foundation. The level of harmony is directly related to the acoustic effect and expressiveness of the accompaniment. The choice of harmony should be considered based on the needs of the specific work, and the arrangement, connection, omission, functionality, color, rhythm, expressiveness, chord structure and overtones, harmony style, etc. should be considered. This has fixed rules in harmony practice, but is very flexible in practical application. There are also problems that cannot be found in practice, but must be dealt with in practical applications. Therefore, the foundation of harmony is very important. Three: Accompaniment type: Once you have mastered a certain foundation of piano and harmony, you must use a certain form to make statements. The accompaniment pattern is a regular statement form that applies the basics of harmony to specific works. Whether this form is appropriate and how to make it appropriate should have a certain basis. Such as the performance of the piano, the characteristics and expressiveness of the accompaniment pattern, the playing method, and the accompanist’s existing piano skills and application ability level, etc. The quality of the accompaniment, in addition to the harmony effect, is also the result of the accompaniment pattern. Applied. Therefore, making good creative choices and designing good accompaniment patterns are essential to playing good improvisational accompaniment. Four: Song analysis: The analysis of song genre, form, musical form, and content is the basis for the appropriate selection of harmony and accompaniment patterns. As far as harmony is concerned, the clarity of tonality, half-term, and termination are important. The chord structure, harmonic effect, and whether the style is consistent with the content of the song are all determined through the analysis of the song. The choice of accompaniment type is also based on the analysis of the song. A beautiful lyrical song and a firm and powerful march must have different accompaniment types. That is, the same song has different accompaniment patterns between each section and The process from presentation to climax reproduction cannot be static. Therefore, it is very necessary to analyze the songs based on the needs of accompaniment, especially the selection and application of accompaniment patterns, which is an indispensable important link. Five: Comprehensive application ability: Comprehensive application ability refers to the synthesis of piano skills, harmony basics, accompaniment patterns, song analysis, improvisational arrangement, cooperation with singers, artistic practice experience, etc. The cultivation and exercise of this ability is the key to being able to play improvisational accompaniment well. In short, improvisational accompaniment is a complex, multifaceted, comprehensive course that combines various elements. But it is not an unfathomable, mysterious book. As long as you continue to learn, you will eventually improve. When playing pop songs, you usually play the main melody with your right hand and accompaniment with your left hand. Of course, the right hand can sometimes add some accompaniment, such as when the melody pauses slightly. Sometimes you can also play arpeggios or broken chords with both hands alternately.
